I'll start, and then I'll ask Mr. Hatfield to add to my answer if necessary.
When we hire someone at the Department of Public Safety and Emergency Preparedness, we always verify the validity of their security clearance, which is transferred. It is also the department's responsibility, when someone comes to work there, to ensure that they can be trusted, taking into account the position they are filling. If it's a position that requires secret or top secret security clearance, it's up to the department to verify the clearance.
In my field, there are more positions that require top secret security clearance. When we have to raise an employee's security clearance level, we must conduct a new background check. We ensure that we follow the policy. As the receiving department, we have a responsibility to verify the validity of the security clearance.
